Thanks Kyle. Learned a bit more of Elisp.

You could collect names with something like

  (require 'subr-x)

  (let (names)
(org-table-map-tables
 (lambda ()
   (when-let ((name (org-element-property :name (org-element-at-point
 (push name names)))
 'quiet)
(nreverse names))

and then pass those as the collection to completing-read.

You could get that with

  (and (org-at-table-p)
   (save-excursion
 (goto-char (org-table-begin))
 (org-element-property :name (org-element-at-point

and pass that as the default for completing-read.

I think that'd be the cleanest way, yes.  You could change

  (interactive "MTable Name: ")

into

  (interactive (list (completing-read ...)))

Transforming table and then exporting as CSV

[Pankaj Jangid]

I have the following requirement. For this I have written the code that
follows.

Bank requires from me a CSV file in this format:

--8<---cut here---start->8---
ACCOUNT NO,DR/CR,AMOUNT,NARRATION
50...658,C,x.xx,APR2021
50...590,C,x.xx,APR2021
50...904,C,x.xx,APR2021
06...965,C,x.xx,APR2021
50...489,C,x.xx,APR2021
50...680,C,x.xx,APR2021
50...357,C,x.xx,APR2021
--8<---cut here---end--->8---

But this doesn’t have names of the people. First column shows the
account numbers. So I have created an org-table like this

--8<---cut here---start->8---
* April 2021
  :PROPERTIES:
  :TABLE_EXPORT_FILE: enet_apr_2021/0684SAL2904.001.csv
  :TABLE_EXPORT_FORMAT: orgtbl-to-csv
  :END:
  #+NAME: APR2021
  | NAME  | ACCOUNT NO | DR/CR |AMOUNT | NARRATION |
  |---++---+---+---|
  | Dhma...arwal  | 50.658 | C |  x.xx | APR2021   |
  | Prar  | 50.590 | C |  x.xx | APR2021   |
  | Oly   | 50.904 | C |  x.xx | APR2021   |
  | Sagid | 06.965 | C |  x.xx | APR2021   |
  | Pagid | 50.489 | C |  x.xx | APR2021   |
  | Maar  | 50.680 | C |  x.xx | APR2021   |
  | Shagi | 50.357 | C |  x.xx | APR2021   |
  |---++---+---+---|
  | TOTAL ||   | xx.xx |   |
  #+TBLFM: $4=$4;%.2f
--8<---cut here---end--->8---

I have written below code for the conversion. This code removes the
first column and last row. And then run ‘org-table-export‘. This works
fine.

#+begin_src elisp
(require 'org)

(defun enet-export (name)
  (interactive "MTable Name: ")
  (outline-show-all)
  (let ((case-fold-search t))
(goto-char (point-min))
(if (search-forward-regexp (concat "#\\+NAME: +" name) nil t)
(progn
  (forward-line)
  (let* ((beg (org-table-begin))
 (end (org-table-end))
 (txt (buffer-substring-no-properties beg end))
 (file (org-entry-get (point) "TABLE_EXPORT_FILE"))
 (format (org-entry-get (point) "TABLE_EXPORT_FORMAT")))
(with-temp-buffer
  (insert txt)
  (goto-char (point-min))
  (org-table-next-field)
  (org-table-delete-column)
  (goto-char (org-table-end))
  (backward-char)
  (org-table-kill-row)
  (org-table-kill-row)
  (org-entry-put (point) "TABLE_EXPORT_FILE" file)
  (org-entry-put (point) "TABLE_EXPORT_FORMAT" format)
  (make-directory (file-name-directory file) t)
  (org-table-export
  (message "Not Found"
#+end_src

Same org file has multiple tables, so I am asking for “Table Name”. I
want to do two improvements:

1. When asking for table name, I want to offer all the table names in
   the file as completion options.

2. Current table at point as default

3. I want to run the function from command line. Like,

--8<---cut here---start->8---
   emacs --batch enet_2021_22.org -l enet.el --eval="(enet-export \"APR2021\")"
--8<---cut here---end--->8---

   Do I need to change the (interactive...) part in any way to enable
   this?
